30 Days Hath...

Did you ever wonder why some months have 30 and others 31 days? We all have to memorize that silly rhyme. But it turns out that originally there was some system to it. Do this. Write down the months as they are:

January

31

February

28/29

March

31

April

30

May

31

June

30

July

31

August

31

September

30

October

31

November

30

December

31

Now give February back the 30 days it originally had (emperors stole its days for their own months). And strike off August altogether (itís a bogus month dreamed up by the megalomaniac Octavian):

January

31

February

30

March

31

April

30

May

31

June

30

July

31

September

30

October

31

November

30

December

31

Now what have we got? A perfect alternation of 31 and 30! Yes, I know — now thereís only 11 months. Letís restore the ancient Roman month Mercedonius, and give it 30 days:

January

31

February

30

March

31

April

30

May

31

June

30

July

31

September

30

October

31

November

30

December

31

Mercedonius

30

By the way, because I know you canít live without this information, here is the September-song rhyme in Latin:

JUNIUS, APRILIS, SEPTEMBER ET IPSE NOUEMBER
DANT TRIGINTA DIES RELIQUIS SUPERADDITUR JUNUS,
DE QUORUM NUMERO FEBRUARIUS EXCIPIATUR

— Ausonius, 4th century Latin writer

P. S. Latin poetry doesnít rhyme.
